DETECTING AND SPARING OF OPTICAL PCIE CABLE CHANNEL ATTACHED IO DRAWER |
| 摘要 |
A method, system and computer program product are provided for detecting state and sparing of optical Peripheral Component Interconnect Express (PCI-Express or PCIE) cable channels attached to an IO drawer. System firmware is provided for implementing health check functions and state detection and sparing functions. One or more optical cables are connected between a host bridge and an PCIE enclosure, each optical cable includes one or more spare optical channels. An identified failed optical channel is rerouted to the spare optical channel. |

1. A method for detecting state and sparing of optical Peripheral Component Interconnect Express (PCI-Express or PCIE) cable channels attached to an IO drawer in a computer system, comprising:
providing system firmware for implementing health check functions and detecting state and sparing functions; providing one or more optical cables coupled between host bridge and an PCIE enclosure, each optical cable including one or more spare optical channels; identifying a failed optical channel and rerouting the failed optical channel to a spare optical channel. |
